Tim, I also found the lambda heater needed feeding directly with a switched live. Initially I wired it up with a relay switched by pin 8 on the E connector like in the Hondata engine swap diagram on the website but it doesn't work for the euro type R. I got hold of the Honda workshop manual and the schematic in there confirms that the primary lambda is fed 12v direct on the orange/black or yellow/black from a switched live rail.

I'd already fitted the relay by this stage so it got re-purposed as part of an immobiliser!
